Three. Count number of zeros. If multiply decimal by 100 move decimal point 2 places, etc.
THREE because there are three zeros in 1000. Power or 10's dude. Powers of 10.
moving the decimal 3 place to the right 1000 have 3 zeros.
Move the decimal three places to the right.
Move the decimal point three places to the right.
You move the decimal point three places to the left - inserting zeros, if required.
As you are multiplying by 1000, move the decimal point three digits to the right (inserting zeros as necessary). The kilo- prefix means 1000. Thus 1 km = 1000 m. So to convert from km to m, multiply by 1000. When multiplying by a power of 10, move the decimal point the same number of digits as zeros in the power to the right. 1000 has three zeros, so move the decimal point three digits to the right (inserting zeros if necessarily).
Multiply by 1000 or move the decimal three places to the right.
It moves three places to the right.
Exactly what you have when you just move the decimal point three places to the right from where it originally is.
Adding the zeros
Converting from litres to millilitres you move the decimal 3 places to the right as the number is getting 1000 times bigger (multiply by 1000)
They are 8 times 125 = 1000
Move the decimal point 3 places to the RIGHT and annex 2 zeros.
To multiply by 1/10, move the decimal point 1 place to the left. To multiply by 1/100, move the decimal point 2 places to the left. To multiply by 1/1000, move the decimal point 3 places to the left.
There are 1000 joules in 1 kilojoules. to convert kilojoules to joules you need to multiply by 1000, this means moving the decimal point three places to the right filling any gaps with zeros. 1.5 kJ becomes 1500 J.
However many places in the decimal is how many zeros the denominator has. 0.34 = 34/100 0.575 = 575/1000
There are 1000 meters in a kilometer, so multiply by 1000 4.8 * 1000 = 4800
Count how many places behind the decimal point. That's how many 'zeros' (10, 100, 1000) you will have to divide it by. Then simplify.
Divide by 1000, or multiply by 10-3, or move the decimal point 3 places to the left
Count the numbers of places after the decimal, divide the decimal value by 1 followed by the as many zeros as there are places after the decimal. Easier to do than to say For example 0.53 = 53/100 0.534 = 534/1000 0.5342 = 5342/1000
It depends what they are fractions of. For fractions of kilograms, simply multiply by 1000 (move the decimal point 3 places to the right).
8 and 125
